Colonies on Karmali agar, CCDA and trypticase soy agar are 0.3–2.0 mm in diameter
at 37 and 40 ºC after 48 hours incubation, whitish-grey in colour with a light centre,
margins are entire and the colony surfaces are typically smooth and flat. Alpha-
hemolysis is negative. Growth on Mueller-Hinton agar is very restricted.
Microaerophilic and anaerobic. Thermophilic. Grow at 37-42 ºC, but not at 25 ºC.
No growth occurs in the presence of 2.0 or 3.5% (w/v) NaCl at 40 ºC. No growth on
Nutrient agar. Can grow on MacConkey agar. Variable growth on 1% glycine (30 % of
